A car travels for 2 hours 15 minutes at an average speed of 64 mph. Calculate the distance travelled.

231.746 km

Step-by-step explanation:

In order to find the answer to this question we will have to answer it using what the question gives us.

The car traveled for 2 hours and 15 minutes

The average speed of the car was 64 mph (miles per hour)

2 hours = 64 + 64 = 128

15 minutes is 1/4 of a hour which means you need to divide miles per hour by 4

64 ÷ 4 = 16 or 16+16+16+16 = 64

128 + 16 = 144 distance total

Since the answer needs to be in kilometers we need to convert miles into kilometers.

We know that..

1 mile = 1.60934 km

Which means you need to multiply 1.60934 by 144 (total number of miles) to find your answer in kilometers.

1.60934 × 144 =231.746km

= 231.746km

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
